The M48T18-100PC1 is a part of M48T18 series Battery Backed SRAM. It has an operating temperature ranging from -40 °C to +85 °C and it comes in PMDIP-32 Packaging.

The M48T18 TIMEKEEPER® RAM is an 8 K x 8 non-volatile static RAM and realtime clock which is pin and function compatible with the DS1643. The monolithic chip is available in two special packages to provide a highly integrated battery-backed memory and real-time clock solution.

Features:

  • Integrated ultra low power SRAM, real-time clock, power-fail control circuit, and battery
  • BYTEWIDE™ RAM-like clock access
  • BCD coded year, month, day, date, hours, minutes, and seconds
  • Typical clock accuracy of ±1 minute a month, at 25 °C
  • Automatic power-fail chip deselect and write protection
  • Write protect VPFD = Power-fail deselect voltage):
    • M48T08: VCC = 4.75 to 5.5 V, 4.5 V ≤ VPFD ≤ 4.75 V
    • M48T18/T08Y: VCC = 4.5 to 5.5 V, 4.2 V ≤ VPFD ≤ 4.5 V
  • Software controlled clock calibration for high accuracy applications
  • Self-contained battery and crystal in the CAPHAT™ DIP package
  • Packaging includes a 28-lead SOIC and SNAPHAT® top (to be ordered separately)
  • SOIC package provides direct connection for a snaphat top which contains the battery and crystal
  • Pin and function compatible with DS1643 and JEDEC standard 8 K x 8 SRAMs
  • RoHS compliant
    • Lead-free second level interconnect
